HLTH 235: Food Systems

Finding Books

A good way to start your research is to search for books, book chapters and eBooks on your research topic.

Search Omni to find books (and other materials) owned by the library.  You may search by topic using keywords, author, title, or subject headings. 

Once you have located a book of interest, use the subject headings to identify additional resources on your topic. 

Use the filters in Omni to refine your search results, by format (e.g. books & eBooks, journal articles, etc.). The filters are located along the left-hand side of the search results screen.

Basic Search Tips

Enter one or more of your topic keywords into the Omni search box and then click the search button. 

Basic search supports the use of Boolean operators: AND, OR or NOT, and they must be entered in uppercase. For example:

  • Covid-19 AND "food security"
  • agroecology OR agri-environmental

Search Tips

To search for a specific phrase, type quotation marks around the phrase.  For example: "food systems"

Truncation is the process of adding an asterisk '*' to the end of a root word to get different variations on the word. For example: environment* for environments, environmental

Narrow or refine search by adding other terms using AND.

For example: Covid-19 AND "food security" AND Africa

Broaden your search results by using OR between similar terms nested in brackets.

For example: (agroecology OR agri-environmental) AND "food systems"

*Please note that the default search in Omni includes the holdings of Queen's University Library AND the physical holdings of our Omni partner libraries in Ontario.

Advanced Search

Use the Advanced Search option for more precise searching. Using the drop-down options within the Advanced Search screen you can limit your search to specific fields and/or a combination of fields (Author, Title, Subject, Call number). You can also specify that your search words must be contained in the search field ("contains", "starts with" or "is (exact)."  


Modify Your Results

You can Modify your search results by using the Filters list on the left side of the search screen. For example, modify your results by Resource Type such as Book Chapters, Books & eBooks.

You can also narrow your search results by selecting relevant subject terms in the Subject Filter.
